That probably wouldn't help since by the time a warhead is that close it's trajectory is on a ballistic path. Plus I'm sure they use gps nowadays and a nuclear device doesn't need pin point accuracy.Bob DeWoody

My motto: Never do today what you can put off until tomorrow as it may not be required. This no longer applies in light of current events.

GPS doesn't work very well at high velocities and high altitudes that ICBM reach during their flight.
Also, as has already been stated a nuclear bomb does not have to "hit" its target - think of the destruction of Nagasaki and Hiroshima, those were small bombs, and they raised areas of tens of square miles. A near miss of even a few miles off-centre by a typical ICBM warhead would render most major cities into nuclear deserts :-(Bob Smith

.....and most ICBM's are multi headed beasts.Old enough to know better(but)still young enough not to care
